Description Patrick Silva 2019-12-04 18:46:56 UTC 
Application: plasmashell (5.17.80)

Qt Version: 5.13.2
Frameworks Version: 5.65.0
Operating System: Linux 5.0.0-29-generic x86_64
Windowing system: Wayland
Distribution: KDE neon Unstable Edition

-- Information about the crash:
- What I was doing when the application crashed:
start Wayland session
open system settings > global theme
set global theme to breeze or breeze dark
plasma crashes

plasma also crashes with the same backtrace when I change font hinting setting in system settings > fonts.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Aborted
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

I can confirm this issue, changing font settings or global theme (and maybe other personalization actions) lead to a Plasma crash. Everything freezes apart from the mouse cursor.

Comment 5 David Edmundson 2020-05-03 10:59:43 UTC 
Yeah, the blur global gets removed just as a client is binding.

Requires support for wl_global_remove which I had to revert because it requires wayland1.8 which stupid distros don't have. 

Maybe I can just fix the symptom and make kwin reload less on a global theme change
Comment 6 Pietro F. Fontana 2020-05-03 11:07:22 UTC 
I am running X.org 1.20.8 and Wayland 1.18.0, the latter packaged by Arch Linux.
I do not know if this is useful information for you.

I also can't reproduce this plasma crash on Arch after update to 5.20 beta.
Now the whole session crashes instead (reported as bug 422424).

LOL that's even worse! Let's keep going there.

Changed global theme (Breeze Dark)
- Custom settings of the application:
"Full Wayland" enabled on opensuse tumbleweed

re-opening as per comment 35.
Comment 37 Vlad Zahorodnii 2021-04-05 20:13:36 UTC 
Can you provide wayland debug please? You will need to run plasmashell with WAYLAND_DEBUG=1 and make it crash.

Comment 45 Nate Graham 2021-04-29 13:53:33 UTC 
So is this confirmed to still be an issue in Plasma 5.22? I can't reproduce it if I change a bunch of stuff in System Settings on Wayland.
Comment 46 lso 2021-04-29 16:19:45 UTC 
Hello!  I think the problem has been fixed at this point, as changing multiple selections
in the System Settings no longer causes a crash.

Thanks!

A bunch of changes went in today that we think will fix this for real this time in Plasma 5.22. :) Closing again, and we can re-open it if people are still able to reproduce the same crash in Plasma 5.22.

Comment 59 Patrick Silva 2021-05-13 20:52:38 UTC 
Plasma no longer crashes on Plasma 5.22 beta when I change global theme.
But at least the following duplicates are still reproducible:

bug 429407
bug 436274
bug 432297
bug 429342
bug 429137

Operating System: Arch Linux
KDE Plasma Version: 5.21.90
KDE Frameworks Version: 5.82.0
Qt Version: 5.15.2
Graphics Platform: Wayland
Comment 60 Nate Graham 2021-05-13 20:56:00 UTC 
Perhaps those are separate issues. Can you re-open the ones that are still reproducible for you and put them in the "See also" list for this ticket? Thanks!
Comment 61 Patrick Silva 2021-05-14 13:48:43 UTC 
Even Plasma is still crashing sometimes on neon unstable.
I was using Breeze global theme, I changed color scheme 3 times in sequence
in Colors KCM, them I changed to Breeze Dark global theme with double-click
on it and Plasma crashed.

plasmashell (5.18.6) using Qt 5.12.7

- What I was doing when the application crashed: 

Changing font  size in settings of KDE Plasma LTS 5.18.6 under Wayland session. 

Bug tracker says that is solved in Plasma 5.22 but I will never get this version in openSUSE Leap.
